Answer: (3p^2 + 1) . (p^3 +4)

Step-by-step explanation:

Area of a rectangle equals length multiplied by width. Given length as 3p^2 + 1 and width as p^3 + 4

[7 points] A sample of 78 anchor bolts was randomly selected and the shear strength (in kips) of each was measured, resulting in
vovangra [49]

Answer:

Step-by-step explanation:

We want to determine a 98% confidence interval to estimate the true mean shear strength of anchor bolts.

Number of sample, n = 78

Mean, u = 4.25

Standard deviation, s = 1.3

For a confidence level of 98%, the corresponding z value is 2.33.

We will apply the formula

Confidence interval

= mean ± z × standard deviation/√n

It becomes

4.25 ± 2.33 × 1.3/√78

= 4.25 ± 2.33 × 0.147

= 4.25 ± 0.34

The lower end of the confidence interval is 4.25 - 0.34 = 3.91

The upper end of the confidence interval is 4.25 + 0.34 = 4.59

b) the confidence interval would still be valid because the number of samples is large(> 30)
